[QUOTE="318lll9740, post: 1737386, member: 35398"] So I got back to my home range and weather was perfect in East Texas. I had a sample pack of the 143 HH. I knew the gun shoots 97gr of rl33 and a 140 NBT fast and at a half moa all day, so I started at 91 thru 97 gr of same powder and a coal of 3.5" with the 143 HH, thats three pressure rings in neck. At 93 the bolt was kinda stiff and slight ejector mark, 94 it was real stiff and ejector marked good. With those two shoots I decided to load the remaining 13 projectiles with 92.1 gr of rl33. That load has zero pressure signs and shot this group at 290 yards [IMG]https://i.ibb.co/qMdgHx6/F000-B8-F6-A9-B0-4286-8581-BC196-F18-E9-EA.jpg[/IMG] Thats .92' at 290 yds, roughly one third moa. I proceeded to shoot next round at 100 yds to see where it hit and it was an inch high of bullseye, then went back to gong at 290 yards and she hits dead center. Without a chronograph I figured its kicking around 3700 fps. Needless to say I ordered another 50 pack of 143s to add to the 8 or nine I had left after load development and verification of zero.
